Hold fast the institutions. Some restrict this to precepts of external polity; but this does not please me, for he points out the manner of standing firm. Now, to be furnished with invincible strength is a much higher thing than external discipline. Hence, in my opinion, he includes all doctrine under this term, as though he had said that they have ground on which they may stand firm, provided they persevere in sound doctrine, according as they had been instructed by him. I do not deny that the term paradoseis is fitly applied to the ordinances which are appointed by the Churches, with a view to the promoting of peace and the maintaining of order, and I admit that it is taken in this sense when human traditions are treated of, (Matthew 15:6.) Paul, however, will be found in the next chapter making use of the term tradition, as meaning the rule that he had laid down, and the very signification of the term is general. The context, however, as I have said, requires that it be taken here to mean the whole of that doctrine in which they had been instructed. For the matter treated of is the most important of all -- that their faith may remain secure in the midst of a dreadful agitation of the Church. Papists, however, act a foolish part in gathering from this that their traditions ought to be observed. They reason, indeed, in this manner -- that if it was allowable for Paul to enjoin traditions, it was allowable also for other teachers; and that, if it was a pious thing [1] to observe the former, the latter also ought not less to be observed. Granting them, however, that Paul speaks of precepts belonging to the external government of the Church, I say that they were, nevertheless, not contrived by him, but divinely communicated. For he declares elsewhere, (1-Corinthians 7:35,) that it was not his intention to ensnare consciences, as it was not lawful, either for himself, or for all the Apostles together. They act a still more ridiculous part in making it their aim to pass off, under this, the abominable sink of their own superstitions, as though they were the traditions of Paul. But farewell to these trifles, when we are in possession of Paul's true meaning. And we may judge in part from this Epistle what traditions he here recommends, for he says -- whether by word, that is, discourse, or by epistle. Now, what do these Epistles contain but pure doctrine, which overturns to the very foundation the whole of the Papacy, and every invention that is at variance with the simplicity of the Gospel?

Footnotes

1 - "Une bonne chose et saincte;" -- "A good thing and holy."

Therefore - In view of the fact that you are thus chosen from eternity, and that you are to be raised up to such honor and glory.
Stand fast - Amidst all the temptations which surround you; compare the notes on Ephesians 6:10-14. And hold the traditions which ye have been taught On the word "traditions," see the notes on Matthew 15:2. It means properly things delivered over from one to another; then anything orally delivered - any precept, doctrine, or law. It is frequently employed to denote that which is not written, as contradistinguished from that which is written (compare Matthew 15:2), but not necessarily or always; for here the apostle speaks of the "traditions which they had been taught by his epistle;" compare the notes, 1-Corinthians 11:2. Here it means the doctrines or precepts which they had received from the apostle, whether when he was with them, or after he left them; whether communicated by preaching or by letter. This passage can furnish no authority for holding the "traditions" which have come down from ancient times, and which profess to have been derived from the apostles; because:
(1) there is no evidence that any of those traditions were given by the apostles;
(2) many of them are manifestly so trifling, false, and contrary to the writings of the apostles, that they could not have been delivered by them;
(3) if any of them are genuine, it is impossible to separate them from those which are false;
(4) we have all that is necessary for salvation in the written word; and,
(5) there is not the least evidence that the apostle here meant to refer to any such thing.
He speaks only of what had been delivered to them by himself, whether orally or by letter; not of what was delivered from one to another as from him. There is no intimation here that they were to hold anything as from him which they had not received directly from him, either by his own instructions personally or by letter. With what propriety, then, can this passage be adduced to prove that we are to hold the traditions which professedly come to us through a great number of intermediate persons? Where is the evidence here that the church was to hold those unwritten traditions, and transmit them to future times?
Whether by word - By preaching, when we were with you. It does not mean that he had sent any oral message to them by a third person.
Or our epistle - The former letter which he had written to them.

Therefore, brethren, stand fast - Their obtaining eternal glory depended on their faithfulness to the grace of God; for this calling did not necessarily and irresistibly lead to faith; nor their faith to the sanctification of the spirit; nor their sanctification of the spirit to the glory of our Lord Jesus. Had they not attended to the calling, they could not have believed; had they not believed, they could not have been sanctified; had they not been sanctified they could not have been glorified. All these things depended on each other; they were stages of the great journey; and at any of these stages they might have halted, and never finished their Christian race.
Hold the traditions which ye have been taught - The word παραδοσις, which we render tradition, signifies any thing delivered in the way of teaching; and here most obviously means the doctrines delivered by the apostle to the Thessalonians; whether in his preaching, private conversation, or by these epistles; and particularly the first epistle, as the apostle here states. Whatever these traditions were, as to their matter, they were a revelation from God; for they came by men who spake and acted under the inspiration of the Holy Spirit; and on this ground the passage here can never with any propriety be brought to support the unapostolical and anti-apostolical traditions of the Romish Church; those being matters which are, confessedly, not taken from either Testament, nor were spoken either by a prophet or an apostle.

(11) Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle.
(11) The conclusion: it remains then that we continue in the doctrine which was delivered to us by the mouth and writings of the apostles, through the free good will of God, who comforts us with an invincible hope, and that we also continue in all godliness our whole life long.

Therefore, brethren, stand fast,.... In the doctrine of the Gospel in general, and in the article of Christ's second coming in particular, and not in the least waver about the thing itself, nor be shaken in mind, and troubled as if it was just at hand; and the rather it became them to be concerned that they stood fast in the truth, and persevered unto the end, since there was to be a falling away, and the mystery of iniquity was already working, and antichrist would shortly appear, whose coming would be with all deceivableness, of unrighteousness; and they had the greater encouragement to continue firm and unmoved, seeing they were chosen from eternity unto salvation through sanctification and belief of the truth, and were called in time by the Gospel to the enjoyment of the glory of Christ in another world.
And hold the traditions which ye have been taught: meaning the truths of the Gospel, which may be called traditions, because they are delivered from one to another; the Gospel was first delivered by God the Father to Jesus Christ, as Mediator, and by him to his apostles, and by them to the churches of Christ; whence it is called the form of doctrine delivered to them, and the faith once delivered to the saints: and also the ordinances of the Gospel which the apostles received from Christ, and as they received them faithfully delivered them, such as baptism and the Lord's supper; as well as rules of conduct and behaviour, both in the church, and in the world, even all the commandments of Christ, which he ordered his apostles to teach, and which they gave by him; see 2-Thessalonians 3:6. And so the Syriac version here renders it, "the commandments": and these were such as these saints had been taught by the apostles, under the direction of Christ, and through the guidance of his Spirit; and were not the traditions of men or the rudiments of the world, but what they had received from Christ, through the hands of the apostles:
whether by word, or our epistle, that is, by "our" word, as well as by our epistle, and so the Arabic version reads; these doctrines, ordinances, and rules of discipline were communicated to them, both by word of mouth, when the apostles were in person among them, and by writing afterwards to them; for what the apostles delivered in the ministry of the word to the churches, they sent them in writing, that they might be a standing rule of faith and practice; so that this does not in the least countenance the unwritten traditions of the Papists; and since these were what were taught them, "viva voce", and they received them from the mouth of the apostles, or by letters from them, or both, it became them to hold and retain them fast, and not let them go, either with respect to doctrine or practice.

Therefore--God's sovereign choice of believers, so far from being a ground for inaction on their part, is the strongest incentive to action and perseverance in it. Compare the argument, Philippians 2:12-13, "Work out your own salvation, FOR it is God which worketh in you," &c. We cannot fully explain this in theory; but to the sincere and humble, the practical acting on the principle is plain. "Privilege first, duty afterwards" [EDMUNDS].
stand fast--so as not to be "shaken or troubled" (2-Thessalonians 2:2).
hold--so as not to let go. Adding nothing, subtracting nothing [BENGEL]. The Thessalonians had not held fast his oral instructions but had suffered themselves to be imposed upon by pretended spirit-revelations, and words and letters pretending to be from Paul (2-Thessalonians 2:2), to the effect that "the day of the Lord was instantly imminent."
traditions--truths delivered and transmitted orally, or in writing (2-Thessalonians 3:6; 1-Corinthians 11:2; Greek, "traditions"). The Greek verb from which the noun comes, is used by Paul in 1-Corinthians 11:23; 1-Corinthians 15:3. From the three passages in which "tradition" is used in a good sense, Rome has argued for her accumulation of uninspired traditions, virtually overriding God's Word, while put forward as of co-ordinate authority with it. She forgets the ten passages (Matthew 15:2-3, Matthew 15:6; Mark 7:3, Mark 7:5, Mark 7:8-9, Mark 7:13; Galatians 1:14; Colossians 2:8) stigmatizing man's uninspired traditions. Not even the apostles' sayings were all inspired (for example, Peter's dissimulation, Galatians 2:11-14), but only when they claimed to be so, as in their words afterwards embodied in their canonical writings. Oral inspiration was necessary in their case, until the canon of the written Word should be complete; they proved their possession of inspiration by miracles wrought in support of the new revelation, which revelation, moreover, accorded with the existing Old Testament revelation; an additional test needed besides miracles (compare Deuteronomy 13:1-6; Acts 17:11). When the canon was complete, the infallibility of the living men was transferred to the written Word, now the sole unerring guide, interpreted by the Holy Spirit. Little else has come down to us by the most ancient and universal tradition save this, the all-sufficiency of Scripture for salvation. Therefore, by tradition, we are constrained to cast off all tradition not contained in, or not provable by, Scripture. The Fathers are valuable witnesses to historical facts, which give force to the intimations of Scripture: such as the Christian Lord's day, the baptism of infants, and the genuineness of the canon of Scripture. Tradition (in the sense of human testimony) cannot establish a doctrine, but can authenticate a fact, such as the facts just mentioned. Inspired tradition, in Paul's sense, is not a supplementary oral tradition completing our written Word, but it is identical with the written Word now complete; then the latter not being complete, the tradition was necessarily in part oral, in part written, and continued so until, the latter being complete before the death of St. John, the last apostle, the former was no longer needed. Scripture is, according to Paul, the complete and sufficient rule in all that appertains to making "the man of God perfect, throughly furnished unto all good works" (2-Timothy 3:16-17). It is by leaving Paul's God-inspired tradition for human traditions that Rome has become the forerunner and parent of the Antichrist. It is striking that, from this very chapter denouncing Antichrist, she should draw an argument for her "traditions" by which she fosters anti-Christianity. Because the apostles' oral word was as trustworthy as their written word, it by no means follows that the oral word of those not apostles is as trustworthy as the written word of those who were apostles or inspired evangelists. No tradition of the apostles except their written word can be proved genuine on satisfactory evidence. We are no more bound to accept implicitly the Fathers' interpretations of Scripture, because we accept the Scripture canon on their testimony, than we are bound to accept the Jews' interpretation of the Old Testament, because we accept the Old Testament canon on their testimony.
our epistle--as distinguished from a "letter AS from us," 2-Thessalonians 2:2, namely, that purports to be from us, but is not. He refers to his first Epistle to the Thessalonians.

Hold - Without adding to, or diminishing from, the traditions which ye have been taught - The truths which I have delivered to you. Whether by word or by our epistle - He preached before he wrote. And he had written concerning this in his former epistle.
